Jiangsu Yinhuan Precision Steel Tube Co., Ltd is a national key high-tech Enterprise, which is invested by Yinhuan Holding Group and China General Nuclear Power Group. There are four wholly owned factories, a joint venture factory and a national project technology center. Since founded in 1992, YINHUAN has improved its core competitiveness through make self-directed innovation and take the research and development of the high performance tubes. In recent years, our company introduces China General Nuclear Power Group, Baosteel, China National Nuclear Corporation, Dongfang Electric and other large state-owned enterprises, formed an alliance through equity cooperation and broke the international monopoly, saved more than 15 billion of construction cost for the nation. Our products not only filled the gap, replaced the imported products, achieved the localization, but also be exported to Japan, Germany, the United States and other developed countries, realized the leap development of the enterprise.

By connecting national strategy consciously, YINHUAN successfully completed Jiangsu -Province major scientific and technological achievements transformation projects twice and Central-Government budget fund projects three times, and implemented "863" project, "973" project. YINHUAN also took on the Research and Development of National Key Material, and developed successfully 24 new products which substituted imported products for thermal power, nuclear power, petro-chemical, aviation and aerospace, rail transportation etc. YINHUAN won 32 patents and compiled 6 national standards and 3 industrial standards. During the period of "11th Five-Year Plan", basing on "Jiangsu Engineering& Technology Research Center of High-Level Special Precision Steel Tube" and "Jiangsu Yinhuan Branch of National Engineering Research Center of Advanced Steel Technology", Yinhuan successfully completed 9 localization major achievements substituting imported products such as localization of key tubes and pipes for (ultra) supercritical thermal power units, tubes and pipes for reactor vessel internals and control rod driving system for 1000 MW nuclear power plants, nickel alloy Inconel 690 U-bending tubes for first set of CPR 1000 steam generator, and high-precision pneumatic tubes for high-speed railway train.

At present YINHUAN invested millions of funds to enforce enterprise strength and contribute to key material for 3 kinds of nuclear reactors of 3rd generation nuclear power technologies and 4th generation nuclear power technologies( it means research and development of AP1000 steam generator Inconel 690 U-bend tubes, high-temperature gas cooled reactor coiled tubes, inter-mediate heat exchanger tubes for fast reactors). YINHUAN have already completed research and development projects for material R&D, technical processes consolidation, key equipments R&D, professional production lines integration etc, and owned key technologies of independent intellectual property. So the technologies solved material problems when our nuclear power technologies developed in China and YINHUAN owns key tubes and pipe qualifications of 3rd generation nuclear power and 4th generation nuclear power technologies for industrialization.

YINHUAN, as a development of domestic enterprises take the promotion of national industry as own duty, coordinate the promotion of key technology and national development strategy. Determined to build a high-end manufacturer possess core competitiveness which is leading domestic and international first-class.
